DRY ORE-SEPARATOR.

Application filed December 16, 1915.

To all whom t may concern Be it known that we, DAVID M. OwINGs, a citizen of the United States, residing at Canton, in the county of Blaine, State of Oklahoma, and WILLIAM R. KINsnY, a citizen of the United States, residing at Bartlesville, in the county of Washington and State of Oklahoma, have invented certain new and useful Improvements in Dry Ore-Separatore; and we do declare the following to be a full, clear, and exact description of the invention, such as willl enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in ore concentrators and more particularly to that class known as dry separators.

The object of the invention is to so construct an apparatus of this character that the ore containing sand will be loosened and retained in loosened condition rendering it possible for the heavier metal particles to settle at the bottom of the separator.

Another object is to provide an apparatus of this character with an air blast passing therethrough and with a plurality of agitators some of which are rotated in one direction with the blast and some in the opposite direction against the blast to prevent the escape of any metal particles and cause them to settle in channels in the table of the separator.

With these and other objects in view, the invention consistsof certain novel features of construction, andthe combination and arrangement of parts as will behereinafter more fully described and claimed.

In the accompanying drawings: Figure 1 represents a side elevation of a separator constructed in accordance with this invention, ready for use. Fig. 2 is a similar view taken from the opposite side of the separator; Fig. 3 is a longitudinal section thereof; Fig. 4 is a plan view thereof; Fig. 5 is a horizontal section taken on line 5-5 of Fig. 3. Fig. G is a transverse section taken on the line 6-6 ofFig. 3. Fig. 7 is a similar view taken on line 7-7 Vof Fig.` 3.

In the embodiment illustrated a supporting base 1 is shown on which is mounted a casing 2 having a mouth 3 at its upper end to receive the ore containing material to be treated. A feeding roller l extends transversely across the bottom of this mouth, the

shaft on which said roller is mounted extending at its opposite ends through the opposite ends of the casing 2 and having a sprocket wheel 5 ixed to one end thereof and a collar 6 to its other end. A crank handle 7 is connected with the endv of the shaft on which the sprocket wheel 5 is mounted toprovide for the turning of the shaft by hand although obviously it may be turned by power if found desirable to do so.

A fan casing 8 is mounted on the base 1 at the rear of the casing 2 and communicates with said casingso that the air blast supplied by the fan contained in the casing will pass through the casing 2 in a manner and for a. purpose hereinafter to be de- ,casing S through which the journals of the fan shaft pass are provided with large openings 15 through which air is drawn into the easing by the fan 9. A pinion 16 is fixed to one end of the fan shaft 10 outside the casing 8 Vand is designed to receive a sprocket'r chain 17 which passes around and also over a sprocket wheel 18 carried by a shaft 19 which extends transversely vof the apparatus outside the fan casing 8 at the rea-r thereof and is here shown mounted in bearings 20 carried by the rear ends of the arms 12. A sprocket pinion 21 is mounted on the end ofsaid shaft 19 opposite to that which carries. the sprocket 17 and is designed to receive a sprocket chain 22 which passes also over the sprocket 5 by means of which motion is imparted to the fan on the turning of the crank handle 7. It will thus be seen that the turning of this crank handle 7 will drive both the feeding roller 4 and the fan 9.

The front end of the casing 2 is inclined downwardly and forwardly as shown at 23 and has a riflie board or spreader 24: removably mounted therein and also inclined downwardly and forwardly. A xed board lico 25 extends under the feeding roller 4l. The lower end of the spreader board 24 is spaced above the base l, but in a plane below the inclined top 23 of the casing, thus providing a discharge mouth between said board and said casing top, as shown in Fig. 3.

An angle iron frame 26 preferably eX- tends around the mouth at the lower end of the casing 2 reinforcing and strengthening the casing at this point and providing an abutment for contact with the inner end of a hood hereinafter to be described.

A removable closure 27 is provided for the inclined front end of the casing 2 being designed to rest on the inclined edges at the top thereof with its lower end engaged with the upstanding flange of the frame 26 whereby said closure is held in operative position, although it may be otherwise secured if found necessary or desirable.

As shown the side walls of the casing 2 have secured thereto the upright let above referred to and an iron angle upright 14 which is spaced laterally from the upright ll at any suitable or desired distance being herein shown arranged adjacent a wooden upright 2. These uprights 1+i and 14 which are constructed of angle irons extend from the base l to the top of the casing 2 and are connected at their upper ends by a cross bar 28 supporting the bearing 29 of the shaft 4l of roller Ll. It is to be understood that the standards le and 14C just described are arranged on both sides of the casing 2 and form reinforcing and strengthening supports for the casing. The base plate l is also shown bound by an angle iron frame l although obviously it need not necessarily be so bound. The upper ends of the pairs of standards le and lei. arranged on opposite .sides of the casing are secured to an angle iron frame 31 which is arranged around the mouth 3 at the upper end of the casing 2.

A concentrating table 32 is arranged in front of the casing 2 flush with the bottom thereof and as shown is composed of a plurality of `boards 33 connected b y bolts 34 extending transversely of the table edgewise through the boards. This table 32 has its side edges bound by angle irons 35 with one of the flanges 36 thereof extending laterally therefrom below the top of the boards of which the table is formed and which are designed to provide a supportinglip for a hood soon to be described. The upper face of this table 32 is provided with a plurality of transversely extending longitudinally spaced channels 37 herein shown having' transversely curved bottoms and any desired number of which may be employed, live being here shown, spaced at a suitable or desired distance apart.

A table inclosing hood 40 is shown and may be composed of galvanized iron or any suitable material, the side walls thereof havthe hood around the edges thereof by bolts or rivets and the other flange of said frame projects laterally outward to form a lip el?) along the side edges thereof which is designed to rest on the laterally projecting flanges 3G at the side edges of the table whereby said hood is securely mounted on thetable when in operative position, it being understood that the hood is of a width corresponding substantially to the width of the table whereby a. close lit is provided. The inner end of the hood l() is flared upwardly and outwardly as shown at all and is made of a size corresponding to the size of the mouth formed at the lower front end of the casing 2 and is adapted to be arranged in contact with the frame 26 which extends around said casing mouth. The ends of the hood 40 are also provided with angle iron frames l5 and 4.6 as clearly shown in Figs. l and 2. the frame 45 being substantiallythe same size as the frame 26 of the casing mouth so that when the hood is disposed in operative position these two frames will abut and form a tight connection between the hood and the casing. The hood LLO is also shown provided with reinforcing bands 47 arranged at longitudinally spaced intervals and which are here shown also in the form of angle irons. two of said bands being illustrated in the present embodiment of the invention. An opening 4.8 is formed in the top of the hood 40 intermediatelythc ends thereof being herein shown arranged between the bands 47 and is provided with a. closure Zi9 which is herein shown mounted to slide in suitable guides 50, although obviously it may be otherwise mounted. This opening 4S is designed to afford opportunity for inspection of the table 32 without neces sitating the removal of the hood.

A plurality of toothed cylinders 5l are shown mounted transversely in the hood l0 at points adjacent the side edges thereof and positioned to register with the channels 37 formed in the table 32 so that when said hood is placed in operative position over the table these cylinders will be arranged in said channels (see Fig. 3) and adapted to turn therein so that the sand contained in these channels is loosened and prevented from packing in the channels7 and is thrown up into the path of the air blast. It will thus be seen that by disposing the agitating cylinders completely within the channels that no obstructions are presented on the upper surface of the table so that the current of air passing thereover is unobstructed iso except for the sand thrown up into its path by said agitators. This sand is carried by said blast over said table and discharged through trie outer end of the hood, any metal particles which may be thrown up by the agitators being deposited on the table and blown into the channels therein disposed in advance of the one from which they were ejected. These cylinders 51, tive oi. which are shown, correspond with the five channels employed in the table 32 having their opposite ends journaled in suitable bearings carried by the angle iron frame 3a which extends along the side edges ot the table. These cylinders project at one end beyond the outer face of one side ot the hood l0 and have secured thereto sprocket pinions 52 over which a sprocket chain 53 is designed to pass, said chain extendingover three of said pinions and under two of them as is shown clearly in Fig. 1 so that when the chain is moved, three of the cylinders will be rotated in one direction and the other two in the opposite direction for a purpose to be described. A sprocket wheel 54 is mounted on the innermost cylinder 51 beyond the sprocket pinion 52' thereof` and on the hub of this wheel 5l is a pinion 55 over which a chain 5G passes and is designed for communicating motion to the cylinders 5l through the chain 53 and the sprockets 52 of said cylinders. The chain 56 also passes over a pinion 57 fixed to the sprocket wheel 5 which is controlled by the crank handle 7 so that on the turning of the crank handle 7 motion will be communicated to the feeding roller 4 and tan 9 and the agi- 4 tating cylinders 51 in the hood 40. From the above description it will be obvious that when this crank handle is being turned and motion communicated to the feeding roller, fan and cylinders just described, that any more which is fed into the separator through the mouth 3 at the upper end ot the casing 2 will pass down over the ritlie board or spreader 24 onto the table 32 and durino' its passage it will cross the air blast whidh is forced out of the casing 2 by the fan 9 through the mouth formed below the rillle board 24: and the bottom of the casing into the hood 4.0 and this air blast will cause the sand or other ore containing material to pass longitudinally through the hood over the table 32, the heavier particles of metal contained therein dropping into the channels 37 of the table while the lighter particles of sand and chan will be blown out through the open front end of the hood. Owing to the turning of the cylinders 51 in opposite directions the metal particles will be retarded in their passage through the hood and prevented from being carried out through the open end thereof until the channels 37 have become filled with metal. Then this occurs which may be determined by inspection of the table through the opening 50 in the hood 40, the operation of the separator is stopped and the hood 4:0 re moved to permit the metal contained in the channels to be removed which may be accomplished in any suitable or desired manner, and alter such channels are emptied the hood is again replaced and the separator is ready for use.

rl`he teeth on the cylinders 51 may be of any suitable or desired construction and are here shown in the torni of spikes 58 projecting radially therefrom in all directions and which serve when the cylinders are rotated slowly in the channels 37 to loosen up the sand which may drop into the channels and thus adapt it to be blown out by the air blast through the hood and permit the metal particles contained therein to drop back into the bottoni of the channel.
